Fortran

(Formula Translation) The first and, for a long
time, the most widely used programming language for numerical
and scientific applications. The original versions lacked
recursive procedures and block structure and had a
line-oriented syntax in which certain columns had special
significance.

There have been a great many versions.

The name is often written "FORTRAN", harking back to the days
before computers were taught about lower case, but ANSI
decreed, in about 1985 via the ANSI FORTRAN Technical
Committee TC, that it should be "Fortran".
